Understanding the release and metabolism of aroma compounds using micro-volume saliva samples by ex vivo approaches

This study investigated the behaviour of key aroma compounds in the presence of human saliva (200 μL) from different individuals (n = 3) submitted or not to centrifugation (whole vs clarified saliva). HS-GC results showed that human saliva strongly decreased the release of carbonyl compounds (aldehydes and ketones). This effect was dependent on i) the structure of the aroma compounds and ii) the saliva composition. Whole saliva exerted a higher...
